IMPROVEMENT IN RECIPROCATING CHURNS.

Specification forming part of Letters Patent No. 135,168, dated April22, 1873; application filed December 7, 1 872.

To all whom it may concern:

Be it known that I, MAGNUS LITTY, of Williamsville, in the county ofRichardson and State of Nebraska, have invented a new and valuableImprovement in Ghurns; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawing making a part ofthis specification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawing is a representation of a sectional view of mychurn. Fig. 2 is a plan view of the same.

This invention has relation to churns and it consists in theconstruction and novel arran gement of the churn-frame, and the devicesfor imparting rotary motion to the dasher, as hereinafter described.

A in the drawing designates a table, supporting a cylindrical movablechurn, B, having a vertical rotary dasher, G, with its upper bearing ina horizontal beam, D, and its lower bearing in the center of twoconnected intersecting bars, 0, which exactly fit within and upon thebottom of the cliurn,thereby centering the dasher-staff. The latter isdesigned to be removable, and for this purpose the beam D is providedwith a mortise at one end, and a tenon at the other. The tenon passesthrough an aperture in an upright, E, while the mortise embraces a neck,6, formed in'a corresponding upright, E. The mortise and tenon are longenough to allow the beam to be moved lengthwise suficiently to removethe tenon from its socket, so that the beam may be lifted for theremoval of the dasherstaff. The lower shoulders at the sides of the neck6 are beveled to allow the end of the beam the necessary tilt. Thedasher has imparted to it a rotary reciprocating motion by means of acord, H, wound around it, and connected at the ends to two posts, I,which are pivoted to the table and vibrated. in opposite directionsalternately by hand. When the beam D is in its proper position it isthere maintained by means of a wedge, H, driven into the mortise, asshown. The cords are attached to the posts or arms I by being passedinto notches in the ends and knotted, as shown. A block, is, fixeduponthe table A, and constructed with a concave recess corresponding tothe form of the churn, serves to steady the latter upon the table.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The notched vibratory alternating arms I with their lower endspivoted to the table A, the rotary churn-dasher G, cord H connectingsaid arms and dasher, and the churn B, combined and arranged asspecified and shown.

2. The Inortised and tenoned beam D,the upright E, the upright E havingbeveled notches, the wedge H, and the removable dasher 0, substantiallyas and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the-presence of two witnesses.

MAGNUS LITTY.
